The R142 is a class of 1,030 new technology (NTT) New York City Subway cars built by Bombardier Transportation for the A Division. Along with the R142As, the cars replaced all of the remaining Redbird trains (R26, R28, R29, R33, R33 WF, R36, and R36 WF).
880 of the R142s are numbered 6301–7180, and the remaining 150 cars are numbered 1101–1250.
The R142 is, along with the R142A, the first model class of the newest generation of IRT cars for the subway system. Bombardier built these cars from 1999 to 2003 in La Pocatiere, Quebec and Barre, Vermont with final assembly performed at Plattsburgh, New York.
There are two types of cars: "A" (cab at one end) and "B" (no cabs). "A" cars are powered with four traction motors each, with the passenger doors opposite each other. The "B" cars are powered by two traction motors at the number-two end, and the passenger doors are staggered (car ends are numbered on the lower body just above the truck). The trains are linked up in 5-car, A-B-B-B-A sets, but also can be linked in sets of 4 cars (A-B-B-A), 6 cars (A-B-B-B-B-A), 9 cars (one 5-car set and one 4-car set), or 11 cars (one 5-car set and one 6-car set).
